It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he said: "The last practice of the Messenger of Allah (peace and blessings be upon him) in the funeral prayer before his death was saying four takbirs." And Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) said four takbirs in the funeral prayer of Sayyidah Fatimah (may Allah be pleased with her); Sayyiduna al-Hasan said four takbirs in the funeral prayer of Sayyiduna Ali (may Allah be pleased with them both); Sayyiduna al-Husayn said four takbirs in the funeral prayer of Sayyiduna al-Hasan (may Allah be pleased with them both); Sayyiduna Ali (may Allah be pleased with him) said four takbirs in the funeral prayer of Yazid al-Mukaffaf; Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said four takbirs in the funeral prayer of his honoured father (Sayyiduna Umar al-Faruq, may Allah be pleased with him); the angels said four takbirs in the funeral prayer of Sayyiduna Adam (peace be upon him); and Muhammad bin al-Hanafiyyah said four takbirs in the funeral prayer of Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) at Ta'if.
The chain of this narration is weak.
